Abstract
There is provided an adsorbent material having adsorptive removal properties of Cs and Sr in seawater, and a method for producing a crystalline silicotitanate suitable for the adsorbent material. The adsorbent material includes one selected from crystalline silicotitanates represented by NaTiSiO.nHO, (NaK)TiSiO.nHO and KTiSiO.nHO wherein x represents a number of more than 0 and less than 1 and n represents a number of 0 to 8; and one selected from titanate salts represented by NaTiO.mHO, (NaK)TiO.mHO and KTiO.mHO wherein y represents a number of more than 0 and less than 1 and m represents a number of 0 to 10. The adsorbent material is produced by a method for producing a crystalline silicotitanate in which a silicic acid source, a sodium compound and/or a potassium compound, titanium tetrachloride, and water are mixed to obtain a mixed gel, and the mixed gel is subjected to a hydrothermal reaction.
